Functions[edit] A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
Once you have defined the function in a function definition, you can call or use it somewhere else in the code. You can easily spot this in the following piece of code, where you define a function that computes the square of the argument and then call it after assigning a value for its argument: script.R.
